Question

method of reduction of metal oxide to metal by electrolytic reduction metal are produced at ?
1)anode
2) cathod
3) at base of the tank
4) none​

Answer 1

Answer :

2) cathod

impure metal is taken as anode and pure metal is made of cathode. The electrodes are placed in acidified aqueous solution of metal salt or molten metal salt. On electrolysis, the metal in anode dissolves into the solution and gets deposited over the cathode. The residue left below the anode in the electro-refining of metal is called anode mud.
